In the fields of life sciences, biomedicine, and analytical testing, the efficiency and accuracy of sample concentration directly affect experimental results. The ZLS-4 vacuum centrifugal concentration equipment developed by Hunan Hexi has become the core equipment for laboratory sample pretreatment, designed with "high efficiency, low temperature, and non-destructive" technology.
1、 Vacuum and centrifugation synergy: breaking through the bottleneck of concentration efficiency
The core advantage of the equipment comes from technological collaborative optimization:
•high vacuum systemUsing a two-stage rotary vane vacuum pump, a vacuum environment of ≤ 2mbar can be quickly established and maintained, reducing the boiling point of water to below 15 ℃ and avoiding denaturation of heat sensitive samples such as proteins and nucleic acids.
•Efficient centrifugal structureEquipped with a 4 × 50ml aviation grade aluminum alloy integrated rotor and a stable speed of 1500rpm, the sample uniformly adheres to the tube wall to form a thin liquid film, greatly increasing the evaporation area and improving the concentration efficiency by 40% compared to traditional methods. It is suitable for synchronous processing of multiple batches.
2、 Precise temperature control+environmentally friendly recycling: balancing performance and safety
ZLS-4 achieves dual breakthroughs in addressing the pain points of traditional devices:
•Surrounding infrared heatingNon contact heating combined with PID intelligent algorithm, with temperature control accuracy of ± 0.5 ℃ within the range of room temperature to 80 ℃, ensuring uniform heating of the sample.
•Efficient condensation recoveryThe low-temperature coil design achieves a solvent vapor recovery rate of over 95%, reducing waste and avoiding volatile solvent contamination in the laboratory, meeting green experimental standards.
3、 Intelligent operation+security protection: adapted to laboratory scenarios
Equipment design fully meets actual needs:
•Convenient OperationThe 7-inch touch screen supports one click setting of vacuum degree, speed, temperature, and running time, and data can be stored and exported to meet the traceability requirements of experiments.
•Multiple ProtectionBuilt in over temperature, over voltage protection, and rotor imbalance detection system, automatic shutdown alarm in case of abnormalities; Stainless steel centrifuge chamber is easy to clean and disinfect, avoiding cross contamination, and suitable for the cleanliness requirements of biomedicine.
4、 Widely used: Empowering multi domain experimental processes
ZLS-4 performs excellently in multiple scenarios: in the field of molecular biology, it is used for DNA/RNA concentration and purification, in drug development to process intermediate and formulation samples, and in environmental detection to enrich trace pollutants in water samples. Its stable performance not only improves experimental efficiency but also ensures the accuracy of results, making it an ideal choice for laboratory sample pretreatment.
